I predict that 60s will come out ahead, even though I voted for 50s. Too many muscle cars and European and Japanese sportscars that are world-renouned came out of the 60s., not to mention luxury sedans.

On the other hand, the regular posters here have very intelligent views that are often not in accordance with the norm. We seem to have a lot of interest in newer Alfa's, MB's, BMWs, Peugeot's, Citroen's and Maserati's, which could tip the balance to the 80s.

NOTE: 30s would be a close second for me.
